Apple tree named ‘Campbell Jonathan’

ABSTRACT

A new and distinct variety of Jonathan apple tree, ‘Campbell Jonathan’ originating as a limb mutation of the  Malus domestica  variety of ‘Robison’, (U.S. Plant Pat. 2,934). This new variety is unique from its parent and other Jonathan cultivars in that it has a very bold pattern of alternating dark red and bright red stripes on the skin of its fruit, unlike its parent which has very faint, thin stripes.

Botanical designation: Malus domestica.

Variety denomination: ‘Campbell Jonathan’.

DESCRIPTION OF RELATED APPLICATIONS

The new variety, ‘Campbell Jonathan’ differs from its parent and other‘Jonathan’ varieties in the following characteristics:

-   -   A. The fruit of the new variety differs from previous ‘Jonathan’        cultivars and its parent in the boldness and coloration of the        striping pattern of the fruit. ‘Snyder’ (U.S. Plant Pat. 2650)        has a “substantially solid color”; ‘Super Jon’ (U.S. Plant Pat.        5,086) is “faintly striped”; ‘Higgins’ (U.S. Plant Pat. 6,406)        has a “faint, dark red stripe”; ‘Thome’ (U.S. Plant Pat. 8,701)        has a “dark red blush”; ‘Jackson’ (U.S. Plant Pat. 10,115) has        “no striping”; the parent ‘Robison’ (U.S. Plant Pat. 2,934), has        “minute faint stripes” whereas the new variety has a bold        pattern of alternating dark red and lighter red stripes.

Malus domestica

BACKGROUND OF THE INVENTION

A new and distinct variety of Jonathan apple tree originating as a limbmutation of the Malus domestica variety of ‘Robison’, (U.S. Plant Pat.2,934) ), hereinafter referred to as ‘Campbell Jonathan’. This new sportis unique from its parent because it has a very bold pattern ofalternating dark red and bright red stripes on the skin of its fruit,unlike its parent which has very faint, thin stripes.

SUMMARY OF THE INVENTION

This new and distinct variety of Jonathan apple tree was discovered at1400 West Washington, Waverly, Mo. 64096 as a limb mutation of‘Robison’, (U.S. Plant Pat. 2,934), in an orchard planted in 1986. Thenew variety was noticed because the fruit was boldly striped incomparison to the parent, which has little or no stripe.

Observations during the next two seasons confirmed that the fruitcolored with a very bold striping pattern The mature fruit of the newvariety finishes to a full red pattern of dark red and light redstripes.

In August of 1996, buds were taken from the original limb and trees forfurther testing were produced by cleft grafting onto existing appletrees. In August of 2006, 400 trees were produced by chip budding on ‘M9NIC 29’ (an unpatented selection) rootstock in Brentwood, Calif. The newvariety has remained true to the description herein contained. The newvariety has not been grown on its own root.
